ULPA Air Filter

PTFE Coated High Efficiency Clap-Free Filter

Main Applications

Widely used in electronics, semiconductors, precision machinery, pharmaceutical, hospital, food and other industries on the high requirements of civil or industrial clean places of the end of the filter.

Product Feature

The polytetrafluoroethylene microporous membrane can be used for atmospheric dust removal, air purification and the like by utilizing the unique characteristics of node fibrillary property, smooth surface, chemical substance resistance, air permeability and water impermeability, large air permeability, flame retardance, high temperature resistance, strong acid and alkali resistance, non-toxicity and the like of the polytetrafluoroethylene microporous membrane. The product prepared by the membrane has high filtration efficiency up to 99.99 percent and is close to zero discharge; Low running resistance and high filtering speed; Long service life and can be repeatedly used, thereby reducing operation cost. It is mainly used for flue gas filtration of various industrial furnaces in chemical industry, iron and steel, metallurgy, carbon black, power generation, cement, garbage incineration, etc. Polytetrafluoroethylene filter membrane, the membrane pore size can be controlled in 0.2 ~ 15 μ m, porosity can reach more than 85%.

Characteristics of PTFE Membrane Material

(1) The biggest characteristic of PTFE film material is high strength, medium strength ptfe film thickness is only 0.8mm, but its tensile strength has reached the level of steel; Moreover, the elastic modulus is lower, which is beneficial for the film material to form a complex curved surface modeling;

(2) The use temperature range is wide, can be used in the temperature range of-70 deg c to 230 deg c;

(3) Has unique optical properties, the incident light during the day into natural temperature light, prevent dazzling, no shadow, light uniform distribution; Almost no ultraviolet light transmission, prevent the interior decoration materials and equipment fade; High reflection performance at night makes the room have excellent lighting effect, reduce power consumption, and can foil a night sky buildings brilliant;

(4) Good self-cleaning, rain can wash out the surface of the attachments;

(5) Has a high light transmittance of 13%, a reflectance of 73% to thermal energy, and little heat absorption amount;

(6) The service life of more than 25 years.


Clapboard-free Filter Product Features:


Is mainly used for filtering air suspended particles under 0.3um, as the end of a variety of filtration system filtration;

Using ultra-fine glass fiber filter material, hot sol as the separator, special aluminum frame, polyurethane two-component sealant, closed-cell sponge sealing strip, spray plastic steel mesh uniform flow plate after strict process refined;

Pleated filter material can form ventilation airflow channel, increase the filter material area and air volume, reduce the resistance of the air supply;

Has the advantages of high filtration efficiency, low resistance, large dust capacity, good uniformity of wind speed, strong versatility, convenient installation, etc.;

Temperature resistance 80 C. Humidity resistance 80%.

Each no clapboard filter before the factory after one by one performance test, ensure the performance index of the air filter; And can according to the user request, manufacture each kind of non-standard specification size and the filtration request air filter.
